How to Measure and Fit a Harness on a Cocker Spaniel
Measure the neck and chest, open the clasp, clip on and check two fingers fit. 28 seconds, start to finish.
The short answer
Measure your Cocker Spaniel’s neck at its base and their chest just behind the front legs, then check both measurements against the size chart. Fit the harness by opening the clasp at the neck, bringing it around rather than over the head, fastening the chest, and checking that two fingers slide comfortably under every strap.
Measuring, step by step
- Neck. Run a soft tape around the base of the neck, where a harness actually sits, not up near the collar line.
- Chest. Measure the widest part of the ribcage, just behind the front legs.
- Write both down. Cockers are typically deeper through the chest than their neck suggests, so the two numbers can point at different sizes. If they do, size on the chest and adjust the neck in.

Fitting, step by step
- Open the neck clasp. The lockable clasp releases so the neck loop opens right out.
- Bring it around the neck. Nothing is pulled over the head or ears.
- Fasten the clasp, then the chest. Neck and chest adjust separately.
- Check with two fingers. Two fingers should slide under every strap without forcing.
